The Trim Tag will have an X33 or X77 on Norwood built Camaros however there are exceptions. Pre X code vehicles and anything built at the VanNuys/LA plant did not use an X-Code. These cars are often confirmed by using engine, transmission and rear end stampings (mostly engine stamping). The Vin will let you know if the car was a V8, V6 and coupe or convertible.
